Brownie's OG Tankless Dive System | Gas-Powered Floating


Description

The Brownie's OG is the original gas-powered floating tankless dive system - designed and built in South Florida since 1969. Instead of hauling heavy scuba tanks onto the boat, the OG floats on the surface while divers breathe through individual hoses, keeping your deck clear and your crew in the water longer. Every OG ships as a complete two-diver system with everything you need to get in the water right away.

Whether you're chasing lobster, maintaining your hull, sharing the underwater world with family, or supporting a commercial project, the OG delivers reliable gas-powered air wherever your boat takes you. With a straightforward oil-less direct-drive compressor, quick-release hose connections, and the ability to simply refuel and keep diving, the OG is built around the realities of real dive days on real boats.


Key Features

  • Floating Tankless Design: Air stays on the surface - no heavy scuba cylinders needed on deck, freeing space for your crew and gear.
  • Oil-Less Direct-Drive Compressor: Brownie's direct-drive design eliminates compressor oil, keeping the powertrain simple and maintenance-friendly.
  • Ready for Two Divers Out of the Box: Every OG includes complete equipment for two divers - hoses, regulators, tow belts, downline, and more.
  • Expandable to Four Divers: Add one or two Basic Add-a-Diver Kits to outfit a third or fourth diver from the same floating platform.
  • Quick-Release Connections (QRS Fittings): Brownie's QRS fittings make connecting, disconnecting, and organizing hoses and diver equipment fast and easy.
  • Refuel and Keep Diving: Bring extra gasoline and extend your dive day without waiting for a battery to recharge.
  • Weight: 66 lbs | Dimensions: 24 x 19 x 20 in: Compact enough to transport and deploy from most recreational and work boats.
  • Built-In Dive Flag Assembly: Intake staff and dive-flag assembly included to meet standard safety and visibility requirements.
  • Parts and Service Network: Replacement parts are available and Brownie's service centers support ongoing maintenance, troubleshooting, and repairs.
  • Made in South Florida Since 1969: Decades of proven design and refinement behind every system that leaves the shop.

Compressor & Engine Options - Which to Choose

  • Single Head - Briggs & Stratton: The most affordable entry into the classic Brownie's experience. Pairs a single-head direct-drive compressor with a reliable Briggs & Stratton engine. A great fit for two divers and flexible enough for light, shallow-water use. Best for value-focused buyers, couples, family diving, and routine boat maintenance jobs.
  • Single Head - Honda: The same single-head direct-drive compressor in a compact, complete OG package, powered by a Honda engine. Ideal for two-diver adventures and buyers who simply prefer Honda reliability and performance.
  • Dual Head - Honda: More compressor capacity for bigger crews and higher breathing demand. The dual-head compressor paired with a Honda engine is the configuration Brownie's recommends when three or four divers are part of the plan - providing greater airflow capacity for heavier demand and deeper or longer dives.

FAQ

What does every OG include?

Every OG includes your selected compressor and engine, the floating system and travel cover, intake staff and dive-flag assembly, standard downline and divider fittings, two diver hoses, two low-pressure regulators, two basic tow belts, and one basic mesh gear bag - everything needed for two divers to get in the water.

Which OG configuration should I choose?

Choose the Single Head - Briggs & Stratton for the lowest starting price and great value for two divers. Choose the Single Head - Honda if you prefer a Honda engine for a primarily two-diver setup. Choose the Dual Head - Honda if you plan to dive with three or four people or need greater airflow capacity for heavier breathing demand.

Can a single-head system support four divers?

It's possible, but Brownie's recommends it only for light breathing in extremely shallow water. Air demand changes significantly with depth, exertion, and each diver's breathing rate. If four divers are part of your regular plan, Brownie's strongly recommends the Honda dual-head configuration for adequate airflow capacity.

How do I add more divers to my OG system?

Start with the standard two-diver OG, then add one or two Basic Add-a-Diver Kits to outfit a third or fourth diver. Each kit includes an additional divider connection, one 20-foot diver hose, one low-pressure regulator with whip, and one basic tow belt.

What is the Safety Bundle and do I need it?

The Safety Bundle adds an individual Spare Air Add-On Kit (3-cubic-foot emergency backup air) and a SEAC Screen wrist-mounted dive computer for each diver in your configuration. It's priced as a bundle with meaningful savings compared to buying the items individually. While not required, it's a smart addition for divers who want an emergency backup air source and real-time dive data.

How long can the OG run on a tank of gas?

Runtime varies depending on the engine, fuel supply, and operating conditions. The key advantage of a gas-powered system is that you can bring extra fuel and refuel on the water to extend your dive day without any waiting - unlike battery-powered systems that require a full recharge cycle.

Are replacement parts and service available for the OG?

Yes. Replacement parts are available for Brownie's systems, and an authorized service center network can support maintenance, troubleshooting, and repairs. This long-term parts and service availability is one of the key advantages of choosing a Brownie's system.

Do I need scuba certification to use the OG?

Brownie's recommends that all divers receive appropriate training before using any surface-supplied air system. Every diver should stay within the limits of their training, experience, and equipment. Brownie's offers free online training resources, and proper dive planning and emergency preparation are essential for safe use.
